* Compo node backdrop works again.
* Compo node previews and backdrop now get correct color management
float to byte conversion.
* Compo nodes got unecessarily recalculated while moving nodes.
* Fix compo node viewer nodes not getting activated correctly.
* Main compo node preview render computations are now outside of
mutex lock, so better for multithreading.
* Tex node outputs did not work in some files loaded from 2.4.
* Change RNA updates to take into account groups that may be shared
between multiple node trees.
Think global, act local!
The old favorite G.scene gone! Man... that took almost 2 days.
Also removed G.curscreen and G.edbo.
Not everything could get solved; here's some notes.
- modifiers now store current scene in ModifierData. This is not
meant for permanent, but it can probably stick there until we
cleaned the anim system and depsgraph to cope better with
timing issues.
- Game engine G.scene should become an argument for staring it.
Didn't solve this yet.
- Texture nodes should get scene cfra, but the current implementation
is too tightly wrapped to do it easily.
This option sets the relative scaling factor to the amount set in the
scene "100%/75%/50%/25%" buttons. It's useful when you've got a fixed
background image, and want to do preview renders at a lesser
percentage, so you don't have to go and change the scale node each
time you change the %.
Also removed unnecessary use of a global from texture node.
Previously if the texture node was not connected directly as the
second input to a node like Mix, the size of the generated image
was initialised to 140x140, which is not that useful. It now is
initialised to the size of the render result if it exists, and if
not, the size of the scene render sizeX/sizeY.
This alleviates bug #7068, which is caused by the displace node
trying to get pixels from a texture node, where the texture node
doesn't contain pixels to cover the entire image (only 140x140)
but it's not really a bulletproof solution...
* refactor copying and freeing of node->storage by handlerizing them.
- freestoragefunc
- copystoragefunc
- node_util.c/h have generic handlers for these.
This will allow python or plugin defined nodes to work as well.
(And fixes compile issues with MSVC in yesterdays commit for nodes)
Code provided by Nathan L.
Fixes in his code:
- free_nodesystem() was called too late (after guarded alloc was closed)
- free_nodesystem() was freeing nodes that were not malloced even
- free_nodesystem was using free, not freeN :)
- the typedefs needed to be malloced yes, to allow duplicate nodes like
group but also for dynamic nodes.
